I am Rajkumar, a proud computer science engineer, currently working full-time as an Application Engineer at CodeChef, ever in awe of the wonders that 0s & 1s could create. I started my development with mainly Android apps made out of Java, then got to explore web technologies such as Laravel, NodeJS, Angular etc.

The software I mostly use are :

  • Jetbrains suite of IDEs for development.
  • Sublime Text for quick text editing.
  • Sublime Merge for complex git stuff.
  • Duckduckgo mostly, Startpage rarely.

Linux ♥ Open Source

Ever since I felt bad/disgusted about using non-activated Windows in my first year of college, I switched to Linux ♥ (Ubuntu initially) and never looked back. During my four years of college, I have hopped between multiple Linux distributions and out of everything, my favourite has been elementaryOS because it’s simple, clean and less intrusive thus letting me be more productive.

Apple 👨🏻‍💻

I am also a huge fan of Apple products, and their obsession in UI detailing & providing a seamless user experience across their products. I currently possess an iPhone XR, and a MacBook Air (i5 10th gen) for my daily personal usage.

Security x Privacy 👻

I have always had a fantasy for exploiting software as much as I loved developing them, and I look forward to learning more about it, especially on web security. Until now, I have reported more than a couple of bugs, and have received bounties worth $400 in total.


I also care/preach a lot about privacy and how it’s exploited these days.

If you are not paying for a product, then you’re the product.
